In this section we discuss the two stability conditions, which have to be
satisfied by stable strange quark matter. The first one is that the energy
per baryon of the deconfined phase
(for \(P=0\)  and \(T=0\) ) is lower than the nonstrange infinite baryonic
matter defined in [1]}, [2]}. Following these works we
impose that:
\(E_{A} \equiv \frac{\epsilon }{\rho _{B}} \le 934 \,\,\, \mbox{MeV}.\)
